Hello Erik,
Have you tried radio.on_track(post_metadata) ?

Hi all,
Happy liquidsoap user here, thank you for a wonderful system!
I'm trying out upgrading from 1.x to 2.x and am running into a problem
with a call to on_track in my old script.
Under liquidsoap 2.0.5 running my script results in:
At sparetire.liq, line 19, char 8-17:
Error 4: Undefined variable on_track
Removing the call to on_track allows the script to run. I'm using it
to pass the metadata from the most recently played track to a python
script which relays it elsewhere for display on a website.
I looked through the documentation and upgrade notes and couldn't seem
to find info about this, my apologies if it's already documented
somewhere!
My complete script looks like (with some things removed):
#!/usr/bin/liquidsoap
set('encoder.encoder.export', ['artist', 'title', 'album',
'composer', 'comment'])
set('log.file.path', '')
set('log.stdout', false)
set('harbor.bind_addr', '127.0.0.1')
url = '
streamuser = ''
streampass = ''
sparetirerandom = nrj(playlist('playlist.m3u', mode='normal',
reload_mode='watch'))
radio = mksafe(sparetirerandom)
def post_metadata(m) =
system("/usr/bin/python3 sparetire_info.py "^quote(m['artist'])^"
"^quote(m['title'])^" "^quote(m['album'])^" "^quote(m['composer'])^"
"^quote(m['comment']))
end
radio = on_track(post_metadata(), radio)
output.icecast(%mp3(bitrate=256, samplerate=44100,
internal_quality=0, id3v2=true), radio,
host='localhost', port=8000, user=streamuser, password=streampass,
description='SPARETIRE radio', url=url, genre='Freeform',
mount='sparetire', name='SPARETIRE radio')
Is there another way I can accomplish passing metadata to my python
script? Thank you!
Erik
